A student was having difficulty remembering which bits of the heart were which, so I made this simple diagram.

Join the mixture to the technique

Just a very simple display.

A simple video illustrating the neutralisation of hydrochloric acid by sodium hydroxide, in terms of symbols.

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called Practicexamquest.

Short , overly simplistic, clunky representation of covalent bond at GCSE level. Me experimenting again. It’s a big file, so it’s probably best just to use the link to Youtube on this page.

This is really just a learning document for me to try out some software. It’s a mess , frankly, but use if you wish. PS. the youtube version is of higher resolution. This can be accessed from this page.

A very simple information sheet to cover the update of the definition of the mole, since most textbooks will now be out of date.

I made a simple Venn diagram to put these into context. Students find this area difficult.

A very simplistic, non stoichiometric top down video of mitochondrial free energy transduction. Work in progress.

I made a whacky film thingy about this.

Whacky narrated video showing how to answer the ‘draw a ray diagram to show the formation of an image by a plane mirror’ type question.
